Favored Weapon (3.5e Feat)

From D&D Wiki

Benefit: Choose one specific weapon in the character’s possession. That character is so familiar with that one specific weapon that the character is better at using it than with other weapons of the same type. The character receives a +1 to Hit and +2 to Damage when using that specific weapon. If the character loses the weapon, they lose this bonus unless they can get another weapon crafted exactly like it, including the same type of enchantment. The DC for someone other than the character to recreate the weapon is DC: 45, DC 40 if the smith made the previous weapon that was used, or DC 35 if the character is recreating the weapon.

Special: This feat can be taken multiple times, but each time is a different specific weapon. This can be taken as a Fighter Bonus Feat.
